... agricultural pollution sources, they receive some of the highest nitrogen deposition rates in North America due ... leaching away. So why would atmospheric nitrogen deposition lead to increased losses ...

The Catskill Mountains receive some of the highest nitrogen deposition rates in North America due to pollutants drifting, and a recent study in this region demonstrates how some forested watersheds ...

... , indicate that predicted effects by these models are overestimated because they ignore the limitation of nitrogen. It makes the current predictions by Earth system models more than twice as high as ...

... , and Elser have had a long-standing collaborative relationship, looking not only at nitrogen deposition, as in this study, but also zooplankton nutrition and a broad range of stoichiometric studies. ...

... Clearly, there is much that we do not know about the extent and timescale of the impacts of this nitrogen deposition on the oceans and the subsequent feedbacks to the climate system,” Duce said. “The ...

... monitored nitrogen fixation rates in the mosses. The studies revealed that when high levels of nitrogen were deposited on the moss cushion from above, a condition typical of young forests, nitrogen ...

... change models. On the basis of these results, the authors warn that the high levels of nitrogen deposited in Europe and North America over the past half century already may have left many soils ...

Increasing levels of nitrogen deposition associated with industry and agriculture can drive soils toward a toxic level of acidification, according to a study published in Nature Geoscience.
